TIE-MOLD.

Specification of Letters Patent. Patented De 18, 1917.

Applicationfiled September 19, 1916. Serial.No.12 0,973.'

To all whom it may concern:

Be it known that I, FREDERICK C. Susanna, a citizen of the United States, residing at Eagle Pass, in the county of Maverick and State of Texas, have invented certain new and useful Improvements in Tie-lVlolds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in tie molds and is particularly adapted for use in connection with molding railway ties and constructed in accordance with those illustrated in my pending application for patent for railway tie, filed December 29, 1915, Serial #69239.

Another object of this invention is to provide a novel mold in which the side plates and end plates are held against spreading movement at their bottom edges thereby insuring the proper form in which the material is cast.

A further object of the invention is to provide a mold which is so arranged after the material is set, the side and end walls may be removed and the cores taken from their position whereupon the tie will set on the bottom or pallet from which the same can be readily lifted. 1

ith these and other objects in view the invention consists in the novel combination and arrangement of parts which will be fully set forth in the following specificacation and accompanying drawings, in wh1ch:

F1gure 1 is a vertical sectional view through a mold constructed in accordance with this invention,

Fig. 2 is a top plan view of the mold,.

Fig. 3 is a transverse sectional view through the center of the mold,

Fig. 4 is a transverse sectional view through the mold taken at a point adjacent one end, and

Fig. 5 is a fragmentary detail perspective view of the bottom wall or pallet of the mold.

Referring to the drawings the numeral 1 designates as an entirety, the pallet of the mold comprising a wall or body 2 formed along its side and end edges with downwardly ofi'set portions 3 to form the grooves 4 in which the side and end walls are seated.

Formed centrally of the pallet is a transversely ll-shaped arched wall designatedby the numeral 5 as clearly illustrated in the drawings. The side walls of the mold are designated by the numeral 6 and are formed with offset portions 7 at opposite extremities which form grooves 8 in which the end walls 9 engage. It will be seen. that the lower ends of the end walls 9 and the side edges are engaged respectively by the walls of the grooves 4 and the walls of the grooves 8 thus holding the end walls against accidental" movement.

In order to provide cores for forming the chambers in which the cushioning blocks are positioned, suitable blocks 10 are provided and have attached to opposite ends the transversely extending strips 11 which form recesses in the tie body in which the retaining strips of the cushioning blocks seat. Formed centrally of each of the cores 10 is a suitable opening 11 through which the bolts 12 extend by means of which the strips 11 are secured in place.

It will be apparent from the foregoing that in use, the mold is assembled in the manner illustrated in Figs. 1 and 2 and the plastic material is poured in the same and allowed to set. After the same has become setit will be apparent that the side walls 6 of the mold may be swung outwardly at their top edges and lifted up out ofthe grooves 4 thus leaving the end walls 9 free to be removed and the bolt 12 is then withdrawn from the opening 11 thereby permitting the strips 11 to be moved and the blocks 10 withdrawn from the recesses formed thereby. After the sides and ends have been removed, it will be apparent that the tie may be lifted from the bottom or pallet and the same will conform to the shape of the inside of the mold.

While in the foregoing there has been shown and described the preferred embodiment of this invention, it is 'to be under stood that such changes may be made in the combination and arrangement of parts as will fall within the spirit and scope of the invention as claimed. It will be understood that suitable clamps 13 are provided for holding the mold in assembled position.

What is claimed is A tie mold comprising a substantially elongated rectangular pallet having grooves formed along its side and end edges on the upper side thereof, side Walls adapted to seat in the side, grooves, the opposing faces of the ends of the side WiliiS provided With grooves, end Walls seated in the grooves in 5 the pallet and receiving the grooves in the opposing faces of the side Walls, a transversely V-shaped arch formed centrally of the pallet on its upper face thereof, cores removably fitted between the side Walls to 10 form recesses in the tie, and transverse strips carried by the side faces of the cores to form grooves in the body of the tie, and means for holding the side Walls and end \vads in position.

in testimony whereof I afiiX my signature 15 in presence of two Witnesses.
